its probably because of dumb users. user makes password with spaces, then tries with without spaces and cant figure out why it wont work...

I don't know why this is getting downvoted. It's pretty easy to have accidently insert leading or trailing whitespace when copying/pasting a password.

(Users should never store passwords in plain text or email them to one-another but the reality is they do.)
